DETAILED DESCRIPTION

Surface treatment appliances, such as cleaning appliances which include reciprocating cleaning heads, are used to clean floors in the home, office, and so on. Applicant has recognized that by providing one or more pads with absorbent and/or scrubbing sections, various advantages may be realized.

According to one aspect of the invention, a pad arrangement includes first and second treatment pads, each with a surface-facing side configured to treat a surface. The pads may be connected by one more connectors. In one embodiment, a first surface-facing side includes at least one absorbent section and a second surface-facing side includes at least one absorbent section and at least one scrubbing section. The presence of scrubbing and/or absorbent sections on the surface-facing sides of the pads allows a user to clean a surface with both sections at the same time. Thus, a user does not have to switch pads, or adjust an appliance to which the pads are removably attachable, to clean different surfaces or to effectuate different types of cleaning. Further, the simultaneous use of different floor-contacting materials (e.g., a scrubbing material and an absorbent materials) can provide effective cleaning. For example, using embodiments of the pad disclosed herein with a reciprocating cleaning appliance, dirt or other particles may be scrubbed from a floor with a scrubbing section, and quickly absorbed by an absorbent section. In a conventional pad mop having a pad with only a scrubbing section, dirt that is loosened may be rubbed on the floor as further scrubbing is conducted.

In one embodiment, the absorbent section of the first surface-treatment side has a different absorbent material than the absorbent section of the second surface-facing side. In one embodiment, the absorbent section of the first surface-facing side is a shag material and the absorbent section of the second surface-facing side includes a terry knit material. This combination of materials provides a high overall absorbency and scrubbing capabilities, while allowing the pad to penetrate small areas to pick up dirt with the shag material.

In some embodiments, the absorbent sections of the first and second surface-facing sides include the same absorbent material. The scrubbing section may include olefin loops to provided scrubbing capabilities. In one embodiment, the second-surface facing side includes a scrubbing section positioned in the center of the pad and absorbent sections adjacent the scrubbing section on two sides. The absorbent sections and the scrubbing section may be perpendicular to an edge of a shorter side of the second pad. Or, the scrubbing section and the absorbent sections may be positioned parallel to a longer side of the second pad.

According to another aspect of the invention, a surface treatment appliance includes an appliance head with moveable members that move relative to the appliance head, and first and second treatment pads with first and second surface-facing sides configured to treat a surface. In one embodiment, the first surface-facing side includes an absorbent section and the second surface-facing side includes an absorbent section and a scrubbing section. In another embodiment, the first and second treatment pads are connected to each other by one or more connectors.

In some embodiments, the first surface-facing 20 a side includes an absorbent section 22 and a scrubbing section 24, while the second surface-facing side 20 b includes only absorbent sections 22. It should be appreciated that the number and position of the scrubbing sections 24 and the absorbent sections 22 in these embodiments may vary, as this aspect of the disclosure is not necessarily limiting. It should also be appreciated that the shape of the absorbent and scrubbing sections 22, 24 on the surface-facing sides 20 a, 20 b may vary.

The absorbent section 22 may include nylon loops, although absorbent sections 22 may be any other material suitable for absorption. In one embodiment, the absorbent sections 22 include a mini-shag material with a plurality of strands or loops having a pile length P of at least 5 mm, as shown in FIG. 5, a side view of the pad arrangement in FIG. 4 along a shorter side 30 of the pads 14, 16. In some embodiments, the strands or loops have a pile length P of between 6 mm and 9 mm. In some embodiments, the strands or loops may have a pile length P of between 2 mm and 10 mm. In still further embodiments, the strands or loops may have a pile length P of between 1 mm and 15 mm, or any other suitable length. In one embodiment, the mini-shag material is 100% polyester, 15.45 oz/yd², with 20 wales by 26 courses per inch. In some embodiments, the mini-shag material is weft terry knit on a course gauge machine 8 to 14 gauge. In one embodiment, the mini-shag material is 100% microfiber polyester, 8 oz. In some embodiments, the microfiber lengths are twisted together to form strands or loops. In one embodiment, the absorbent sections 22 include an absorbent material that has any suitable density, for example a density of between 0.01 grams per cm³ and 0.2 grams per cm³, though any other density may be used. In some embodiments, the absorbent sections 22 include a quilted absorbent material. The absorbent section 22 may also be a terry knit material, although other absorbent material may be used as this disclosure is not limited in this regard.

The scrubbing sections 24 may include a non-absorbent material. In one embodiment, the scrubbing sections 24 include olefin and in another embodiment, the scrubbing sections 24 include a plastic material. In one embodiment, the olefin is 100% olefin, 489.9 g/m, with 16.5 wales by 27.0 courses per inch. In some embodiments, the wales are parallel to the edge of the longer side 28 of each pad 14, 16. In other embodiments, the wales are parallel to the edge of the shorter side 30 of each pad 14, 16. In one embodiment, the olefin loops have a height O of at least 1mm, as shown in FIG. 5. The olefin loops may be configured to be parallel to the edge of the longer side 28 of the pads 14, 16, or parallel to the shorter side 30 of the pads 14, 16. In other embodiments, the scrubbing section 24 may include polyester, polypropylene, or any other material suitable for agitation as this disclosure is not limiting. In some embodiments, the scrubbing sections 24 have a low coefficient of friction. In one embodiment, the scrubbing sections 24 are quilted. The scrubbing section 24 also may include any other suitable material for agitating a carpet, such as a material having a rake or teeth. In some embodiments, the scrubbing section 24 may include an abrasive sanding material such as sandpaper.

In some embodiments, the absorbent sections 22 and/or the scrubbing sections 24 are stitched to further connect layers of the pad to one another and/or to provide a material surface with slightly varying height. In some embodiments, the stitching may form a pattern. The stiches may extend from the exterior edges of the first and second pads 14, 16 to the opposed fabric edges at a 30 degree angle, a 45 degree angle, a 60 degree angle, or any other suitable angle, and may form a pattern of crossing stitch lines. In one embodiment, the cross patterns form quadrilateral shapes such as diamonds, or other polygon shapes. In some embodiments, the stitching limits or prevents a sliding of the pad layers relative to one another. Such sliding, if not limited, may reduce a pad's effectiveness at transmitting motion to the carpet.

In some embodiments, the absorbent sections 22 are separate from the scrubbing sections 24. For purposes herein, a separate section does not necessarily mean that a first section is distanced from a second section. Instead, separate sections, such as sections 22 and 24 in one embodiment, may be immediately adjacent to one another and be considered separate sections. In some embodiments two types of material overlap one another, but if each material has a portion that does not overlap with the material, there would still be considered to be two separate sections.

The pad arrangement 10 includes one or more connectors to connect the pads in some embodiments. The connectors 18 may be made of elastic straps, elastic cords, or any other suitable material for connecting the pads and maintaining their relative positions. The connectors 18 also may be made of any other suitable material for permitting the first and second pads 14, 16 to move relative to one another when attached to the moveable members 8. In some embodiments the elasticity of the connectors 18 is greater than the elasticity of the first and second pads 14, 16. The elasticity of the connectors 18 also may be configured such that the first and second pads 14, 16 can move relative to one another, irrespective of the positions of the moveable members 8, when the pad arrangement 10 is attached to the appliance head 6. In some embodiments, the connectors 18 may not necessarily pull the treatment pads 14, 16 toward one another. For example, the connectors may be made of a non-elastic material such as string. In embodiments where the connector(s) do not include elastic material, the pad arrangement 10, and in particular the connector(s) 18, may be sized such that the arrangement 10 is sufficiently long to remain attached to the moveable members 8 when the moveable members 8 are in their outermost position on the appliance head 6. Although two connectors 18 are shown in FIGS. 2-4, in other embodiments one connector or more than two connectors may be used. In some embodiments, the connectors 18 may be made of the same material as the surface-facing sides 20 a, 20 b of the first and second treatment pads 14, 16. The connector(s) 18 also may be integral to the first and second pads 14, 16.

In some embodiment the pad arrangement 10 includes a binding 26 that extends around the edge of the shorter and longer sides 28, 30 of the pads 14, 16. In some embodiments the binding includes a twill material. The surface treatment pad arrangement 10 also may include a tab 32, that extends outwardly from either or both of the first and second pads 14, 16 to allow a user to remove the pad arrangement 10 from the appliance head 6. It should be appreciated that the tab 32 can be located on any of the exterior edges of the pad arrangement 10 and that the pad arrangement 10 can have more than one tab 32. In one embodiment, the tab 32 may be integrated as part of the pad itself. The pad arrangement 10 also may be oversized to provide an area on which a user can step. In such an embodiment, a portion of either or both of the first and second pad 14, 16 extends beyond the appliance head 6 to allow a user to remove the pad arrangement 10 from the appliance by grasping or stepping on the portion.

According to some embodiments, a method of treating a surface with the appliance 2, includes placing the pad arrangement 10 on a surface to be cleaned with the surface-facing sides 20 a, 20 b of each pad 14, 16 in contact with the surface, and placing the appliance head 6 on top of the attachment sides 12, 12 b of the pad arrangement 10. In one embodiment, the scrubbing sections 24 the absorbent sections 22 on the surface-facing sides 20 a, 20 b treat the surface at the same time.
